If it gets any worse (the yellowing) move the light up. They look ok to me. I bleached my plants pretty good under a "shitty" bluprle light, having it at the recommended height. I moved as high as I could I'm my tent since then.
That's what I said, but almost everyone on here was like "don't but that, don't buy that" it's working well for me. I got 2 mars 300 for 150 shipped, wasn't bad IMO. When the panels crap out I'll upgrade them to Quantum or make a CON array out of it.Mars leds are not crap, they are actually an awesome cheap light
They aim themselves at the cheaper budget market; for what you get its a great light.
It's not even a question vs COB, I think a quantum panel would be better, but at 75$ vs $75 I'll take a complete light, especially on my first few grows.They aim themselves at the cheaper budget market; for what you get its a great light.
If you buy one expecting them to grow as well as cobs you will be dissapointed
Id buy a mars or any of the half decent low grade led panels. Cobs have made the lower spec leds very cheap and they compare to t5's and cfls so great for a small veg tent or mother plant.
